G. E. DATH May 16, 1950 HINGE Filed Feb. l0, 1945 Patented May 16, 1950 UNITED STATES ATLENT OFFICE HINGE George E. Dath, Mokena, Ill., assigner to W. H.

Miner, Inc., Chicago, Ill., a corporation of Dela- Ware 4 Claims.

This invention relates to improvements hinges for swinging doors or closures,

One object of the invention is to provide a hinge structure for swinging doors comprising cooperating hinge strap and butt members pivotally connected to each other, wherein the parts are held assembled and pivotally interlocked when the hinge structure is in place on the door and door frame.

A more specific object of the invention is to provide a hinge comprising strap and butt members having cooperating hinge eye and pin portions, wherein the hinge pin portion is formed integral with one of said members, and the other member is composed of a pair of superimposed interlocked sections having the eye portions formed partly on each, section and embracing the hinge pin to operatively secure said hinge members together when the sections are interlooked.

A further object of the invention is to provide a hinge structure, as set forth in the preceding paragraph, wherein the parts o1. the sectional member are maintained in their interlocked relation by the usual hinge securing elements for mounting the hinge in place.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawing forming a part of this speciiication, Figure 1 is a broken elevational View of a portion of one of the walls of an automobile truck provided with swinging doors, illustrating my improved hinge in connection therewith. Figure 2 is a plan View of the improved hinge illustrated in Figure 1, on an enlarged scale. Figure 3 is a plan view of one of a pair of plate elements, which together form the butt member of my improved hinge. Figure 4 is a plan view of the other plate element of the pair forming the butt member. Figure 5 is a plan view, partly broken away, of the strap member of my improved hinge. Figures 6, 7, and 8 are horizontal sectional Views, corresponding respectively to the lines 5*-6, I-, and 3 3 of Figures 4, and 5. Figure 9 is a horizontal longitudinal sectional view, correspending substantially to the line il-9 of Figure 2.

In said drawing, it! indicates a portion of one of the walls of the body of an automobile truck provided with a door opening il, closed by a pair of hinged doors I2 and i3.

As shown in the drawing my improved hinge comprises broadly a hinge leaf or strap A secured to the door; a hinge pin B formed integral with the strap; and a two part sectional hinge leaf or butt C secured to the door post.

The hinge strap A is in the form of an elongated flat plate having the usual screw receiving openings !li-i i for attaching the hinge. .At the inner end, the strap A is laterally enlarged or widened, as indicated at l5, said widened portion being cut out or recessed, as indicated at l5, thus providing two laterally spaced, parallel tongues I'i-l'i. The hinge pin B, which is formed integral with the strap A, comprises an elongated, cylindrical member, extending transversely of the strap at the extremities of the tongues Il Il, being rigidly secured to the latter, preferably by being welded to the end edges of said tongues. As shown most clearly in Figure 5, the pin B spans the opening i5 and projects beyond the opposite sides of the widened inner end portion il of the strap The sectional hinge strap or butt C comprises a pair of superimposed, substantially ilat plates I8 and i9. As shown in the drawing, the plate IS is superimposed upon the plate i8, the latter thus forming a back plate member, and the former a front plate member of the composite hinge butt C. The plates I3 and I 9 are of substantially rectangular outline and of the same size, being of greater width than length. When the plates I3 and I9 are secured together by fastening the hinge butt in place, they are in true registration. The plate IB is provided at its inner edge with a plurality of hook-shaped part eye portions 2li, which are preferably three in number and equally spaced apart transversely of the plate. The spaces between the part eyes ZiB-ZO-Z are of such a size that the tongues i'l-i'l nt freely therein with sufcient clearance to permit free swinging movement of the hinge strap with respect to the hinge butt. The plate i9 is vprovided at its inner edge with a part eye member 2l, which is in the form of a curved channel. The curvature of the part eye member 2l is reverse to that of the part eye members 2li. Adjacent the part eye member 2l of the plate i9, elongated slots or openings 22-2'2-22 are provided which are spaced so as to accommodate the hook-shaped eye portions 2-2-2 of the plate The plate i9 is superimposed on the plate I8 with the part eye portions 20-26--29 of the plate I8 engaged through the openings 22-22-22 and extending over the channel shaped eye portion 2i of the plate iS. The hinge pin B is embraced between the eye portions 28 and Zi of the plates i3 and I9, thus connecting the strap A and the hinge butt C for pivotal swinging movement. The plates I8 and I9 are provided with aligned openings 23-23 Which extend therethrough, adapted to receive the usual headed securing elements 24, which may be in the form of rivets or screws, for securing the hinge butt C, comprising the plates Hl and I9, to the door post or frame. As will be evident, when the hinge is mounted in position on the door and door post, the securing elements 2G for the hinge butt C serve to clamp the plates I8 and I 9 together, thereby maintaining the parts of the hinge in their assembled relation.

I claim:

1. In a hinge, the combination with a hinge strap having an integral hinge pin member; of a hinge butt comprising superimposed front and back plates secured together by fastening elements extending therethrough; and a hinge eye portion formed on each plate, the hinge eye portion of said respective plates together forming a complete hinge eye surrounding said hinge pin, the hinge eye portion of said back plate extending in front of the hinge eye portion of the front plate and engaging over the front side of the pin, and said eye portion of the front plate engaging the rear side of the pin.

2. In a hinge, the combination with a hinge strap having an integral hinge pin; of a hinge butt comprising superimposed front and back plates secured together by fastening elements extending therethrough; and a hook-shaped part hinge eye portion formed on each plate, the hookshaped hinge eye portion of said back plate extending in front of the hinge eye portion of the front plate, said hooked hinge eye portions em- 1,

bracing the hinge pin at opposite sides to pivotally connect the strap and butt.

3. In a hinge, the combination with a hinge strap having an integral hinge pin; of a hinge butt comprising superimposed front and back plates secured together by fastening elements extending therethrough; a hookfshaped part hinge eye portion formed on said front plate, said front plate being slotted adjacent said eye portion; a plurality of hook-shaped hinge eye portions formed on said back plate extending through the slots of the front plate into overlying relation with and in front of said eye portion of the front plate, said hook-shaped portions of the front and back plates embracing the hinge pin of the strap, thereby pivotally connecting the hinge strap and butt.

4. In a hinge, the combination with a hinge strap having an integral hinge pin; of a hinge butt comprising superimposed front and back plates secured together by fastening elements extending therethrough; a hook-shaped part hinge eye portion of channel formation on said iront plate, said front plate having openings therethrough adjacent the eye portion thereof; and a plurality of hook-shaped part hinge eye portions formed on said back plate extending through the openings of the front plate into overlying relation with and in front of said eye portion of the iront plate, said eye portions of said front and back plates embracing the hinge pin, thereby pivotaliy connecting the strap and butt.
